IH 30 west at IH 369 - Texarkana, TX
The systems interchange joining IH 30 and IH 369 at Texarkana, Texas. 05/20/14

Texarkana was originally served by just Interstate 30, which runs east from Dallas, Texas and Little Rock, Arkansas. The addition of IH 369 along the west side of the city in November 2012, and Interstate 49 on the east side in November 2014 establishes the city as a regional transportation hub.

I-35E north - St. Paul, MN
Speed limits along Interstate 35E through St. Paul drop to 45 miles per hour from Exit 103B northward to I-94. 04/21/07

The portion of Interstate 35W northeast along 7th Street SW and the Mississippi River into Downtown St. Paul was the last to be completed in Minnesota. The freeway was designed as a parkway with lower speed limits as part of a compromise for its completion.
